LUBRICATO R.

SPECIFICATION forming part of Letters Patent No. 449,634, dated March 31, 1891.

Application filed October 9, 1390.

To aZZ whom it may concern:

Be it known that we, THOMAS'B.1VICNIEOE and WILLIAM H. BLOOM, citizens of the United States of America, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Lubricators, of which the following is a specification.

Our invention relates to the portable type of sight-feed lubricators, and is intended to simplify the general construction and arrangementof the parts of such lubricators as they are now made.

The invention includes an oil-reservoir, a bracket supporting the sight-feed tube, a condenser, and a single connection for attachment to the steam-pipe, said connection having two channels controlled by independent valves, through one of which channels passes the oil to the parts to be lubricated and through the other the steam forming the water of condensation for the displacement of the oil.

In the accompanying drawings, Figure 1 represents a side elevation of the cup with parts in vertical section. Fig. 2 is a section on line y y of Fig. 1. Fig. 3 is an elevation, partly in section, on line a: a; of Fig. 2.

The oil-reservoir in the drawings is shown at A, and is supported upon the end of a bracket which not only supports the cup, but also forms the entire support for the sightfeed tube. An opening extends from the bottom of the cup through the part a of the bracket, this being closed by a screw-threaded plug 1), having its upper end threaded and made cone-shaped and provided with ports leading to a central passage 0, through which the contents of the cup may be drained when it is desired to clean the same. From the part a of the bracket a branch extends horizontally and is provided with a suitable fitting adapted to receive and support the lower end of the sight-feed tube, and a vertical branch (1 extends upward along the side of the cup, being provided with a fitting for the upper end of the sight-feed tube, and this branch extends outward beyond the line of the sight-feed tube, terminating in a screwthreaded projection which is adapted for connection to the steam-pipe. The screwthreaded projection e of the bracket thus Serial No. 367,529- (No model.)

forms a single connection between the cup and the steam-pipe, and it is provided with two channels, the one 6' leading to the pipe 9 and the condenser 71, and the other m com municating with the sight-feed tube. The channel 6 is controlled by a valve f, and when said valve is open the steam passes through the pipeg to the condenser, and this communicates with the cup through a pipe 1 and the channel Z through the bracket, so that the water of condensation passes into the cup from the condenser and displaces the oil until it overflows the pipe K, which is in connection with the lower part of the cup and with a channel which passes through the' horizontal branch of the bracket to the sight-feed nipple, which issupported in a fitting similar to that included in Letters Patent granted to T. B. McNiece, dated July, 1888, and from this nipple the oil ascends in drops plainly visible through the glass tube and passes out through the second channel m in the single connection to the steam-pipe and thence to the parts to be lubricated. This channel has its controlling-valve f. It will be observed that the bracket is in one piece with the exception of the fittings, and forms the sole support for the sight-feed tube and for connection to the steam-pipe, the cup being supported thereby. The valve 00 controls the flow of the oil to the sight-feed nipple.

Instead of forming a channel Z through the vertical arm of the bracket, the connection i may lead from the condenser directly to the interior of the cup, as indicated in dotted lines.

WVe claim as our invention- 1. In combination, the oil-reservoir, the sight-feed tube and condenser, a vertical bracket having lateral branches extending on one side having removable fittings, the said sight-feed tube being arranged vertically and removably between the said horizontal branches,-0ne of which is extended and screwthreaded to connect with the steam-pipe, the said bracket also having an extension at for the oil-reservoir, and Valves controlling passages through the bracket for the steam and oil, substantially as described.

2. In combination, the oil-reservoir, the sight-feed tube and condenser, the vertical bracket having a passage for the Water of condensation and having a lateral extension nlnnicating with the sight-feed tube and eon- (L at its lower end for the oil-reservoir and an denser, substantially as described. oil-passage, a second lower extension for the In testimony whereof we affix our signalower end of the sight-feed tube, and an extentn res in presence of two Witnesses.
